Now I am going back and forth with the idea I am confused right now on what I want to do I really want to do the guppies, but also now I really want to do the mollies. Would it be ok to let the guppies breed in a 20 us gallon with 1 cory catfish and a couple platies and if I bred the mollies in a 29 us gallon I have with 7 albino cory catfish in there? Or do you think I should just stick to 1 breed right now?
